Fully-sealed pull-type pole-mounted isolating switch

The invention relates to the technical field of electrical switches, in particular to a fully-sealed pull-type pole-mounted isolating switch which comprises a static contact and an insulating shell with an upward opening. The device is reasonable and compact in structure and convenient to use, the moving contact and the static contact can be always kept in a closed state under the pre-tightening force of the pressure spring, and the moving contact insulating pull rod is prevented from falling off and opening due to the influence of the dead weight and vibration of the moving contact insulating pull rod; through the adjusting groove, the long sliding groove, the short sliding groove and the clamping teeth, the opening and closing states of the isolation switch can be reliably controlled. The sealed cavity formed by the static contact and the insulating shell can effectively prevent the static contact and the moving contact from being in contact with dust, rain, snow, ice and the like, so that dust deposition,
